Aim: How do we use Bernoulli's Theorem to solve problems involving "at most" and "at least"?
At the end of this lesson, you will be able to...
investigate the meaning of "at least" and "at most"
express at least and at most Bernoulli experiments as the sum of the appropriate probabilities
solve Bernoulli problems involving at least and at most
Today's lesson builds upon yesterday's lesson. We will still use Bernoulli (binomial distribution) to solve.
Answer these two questions
1. What does "at least mean"?
2. What does "at most" mean?
3. Write the formula for "at least' and 'at most'?
This is for "at least" and "at most". Notice how he lists his variables first, then he uses the formula.
Classwork: Answer the following problem. Be sure you set up your variables first.
Find the probability that when nine dice are tossed,5 will show up on at most 7. (Ans: 0.9999954355)
